** Description changed: **Title:** Dell Latitude 5590 suspend/resume regression in Ubuntu kernel 7.0.0-38 (6.17.0-42 works) **System** - Hardware: Dell Latitude 5590 - BIOS: Dell 1.41.0 - Distribution: Linux Mint 22.3 Cinnamon (Ubuntu 24.04 base) - Graphics: Intel Kaby Lake integrated graphics, i915 driver, PCI device 8086:5917 - Secure Boot: Disabled **Problem** The laptop fails to resume from suspend when running kernel 7.0.0-38-generic. The machine becomes unresponsive, sometimes with the Caps Lock LED flashing repeatedly. Recovery requires a forced power-off. The problem occurs with both `deep` (S3) and `s2idle` suspend modes. **Kernel comparison** - 6.14.0-37-generic: Suspend/resume succeeds. - 6.17.0-42-generic: Suspend/resume succeeds. - 7.0.0-38-generic: Suspend/resume fails. The BIOS was updated from 1.38.0 to 1.41.0 without resolving the problem in kernel 7.0. **Power-management diagnostics under kernel 7.0** - `pm_test=devices`: Successful. System returns automatically after five seconds. - `pm_test=platform`: System hangs; Caps Lock LED flashes approximately twice per second. - Normal suspend: Fails to resume. The last persistent journal entry before one failure was: `PM: suspend entry (deep)` Another failure ended at: `PM: suspend entry (s2idle)` **Additional observations** Kernel 7.0 logs repeated Intel i915 graphics messages, including: - `CPU pipe A FIFO underrun` - `CPU pipe B FIFO underrun` - `DPLL 1 not locked` - `i915_hotplug_work_func` exceeding the workqueue reporting threshold These errors appear during startup as well, so their relationship to the suspend failure is unconfirmed. **Expected behavior** The system should successfully suspend and resume as it does under kernels 6.14.0-37 and 6.17.0-42. **Actual behavior** Under kernel 7.0.0-38, the system hangs and requires a forced shutdown. **Workaround** Boot kernel 6.17.0-42-generic, which successfully resumes from suspend. **Request** - Please investigate a possible regression affecting ACPI/platform suspend - or associated device power management between the 6.17 and 7.0 kernel - series. + Please investigate a possible regression affecting ACPI/platform suspend or associated device power management between the 6.17 and 7.0 kernel series. + --- + ProblemType: Bug + ApportVersion: 2.28.3-0ubuntu0.1 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: zer0 1208 F.... wireplumber + /dev/snd/seq: zer0 1206 F.... pipewire + CRDA: N/A + CasperMD5CheckResult: pass + CurrentDesktop: X-Cinnamon + DistroRelease: Linux Mint 22.3 + InstallationDate: Installed on 2026-10-20 (5 days ago) + InstallationMedia: Linux Mint 22.3 "Zena" - Release amd64 20260108 + Lsusb: + Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub + Bus 001 Device 002: ID 1ea7:0064 SHARKOON Technologies GmbH 2.4GHz Wireless rechargeable vertical mouse [More&Better] + Bus 001 Device 003: ID 0c45:6717 Microdia Integrated_Webcam_HD + Bus 001 Device 004: ID 0cf3:e007 Qualcomm Atheros Communications + Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub + MachineType: Dell Inc.
